LIGHTING-FIXTURE.

. Be it known that I, EDWIN L. WHITE, a citizen of the United States,residing at the borough ofBrooklyn, county of Kings, in the city andState of New York, have invented an Improvement in Lighting-Fixtures, ofwhich the following is a specification.

Myinvention relates to li hting fixtures, and particularly to holders orlight transmitting shades or bowls of the character illustrated anddescribed in my application filed May 19th, 1917, Serial No. 169,610,the present invention being an improvement upon that device. Holders ofthis character .prior to my'said earlier invention had been madecomprising a ring-shaped top adapted for connection with a socket coveror shell provided with set screws for clamping the ring, and with twodownwardly extending oppositely bowed arms connected at their upper endsto the ring by solder or rivets and at their lower ends in the samemanner to a dish-shaped bottom, which holders were placed inside thebowl whose bottom rested within a cup secured to the inner dishshapedmember. My prior application above referred to relates to providing astrong and secure attachment of the arms to the top ring, and anunbreakable connection .between the lower ends. of the arms in suchmanner as to render the employment of the the old style of bottomconnection may be used, the object of my present invention being toprovide means for connecting the holder directly to a lamp-socketdispensing with a cover for the socket and the set screws required wherethe upper ends of the arms of the holders have been attached to a ringconnected to a socket cover or shell.

In the accompanying drawing:

Fig. 9 is a fragmentary section in enlarged size to moreclearlyillustrate the holder as clamped to the socket.

Similar reference characters indicate like parts throughout the severalviews.

10 and 11 denote two oppositely disposed and more or less bowed armseach provided at its upper end with a horizontal semicircular extension12, these extensions being oppositely curved on the respective arms.

Each arm for a predetermined distance below the extension is preferablybent vertically in a straight line and somewhat fiattened, thesemi-circular extensions also being preferably flattened; the ends ofthese extensions meet forming a ring. These curved portions arepreferably made intogral with the arms, but may be madeseparate andattached in any suitable manner.

The lower ends of the arms 10 and 11 are preferably bentand securedwithin recesses in the hub 13 as shown and described in my aforesaidapplication.

14, indicates a bowl the bottom of which rests within or upon the cup15, which is provided with a central hole for the passage 3 18, denotesa lamp-socket of the ordinary character, provided at its lower part withan annular rib 19.

20, indicates the coupling ring by means of which the globe holdingdevice is connected to the lamp-socket 18.

This ring is of sheet metal with outwardly curved lower part, and ispreferably pro vided with an inturned annular flange 21 at the top, andannular rib 22, at the bottom to give rigidity and strength.

Between the top of the ring and the bottom rib thereon, a plurality ofspaced U- shaped cuts are made, forming a plurality of spaced springfingers 23.

Each of these fingers is provided on its inner surface with a transverseshoulder or projection 24. These projections are formed by bending thefingers inwardly at or near their longitudinal center and thenoutwardly, thus leaving the lower ends of the fingers curved outwardlyas shown.

In connecting the bowl holding device to the socket, the ring 20 isfirst placed over the lower end of the socket 18, This end of the socketis then passed between jthe semi circular extensions 12on the upper endsof the arms and ll iiherebeing 'sufficient semi-circular extensionthereon, after which 12, when they spring inwardly, the :proj'ec--.-tions '24: catching under'the bottom edges venting any possibility ofthesocket being pulled; out until the coupling ring- -is released.

the ends. of the semi-circular extensions are .again brought togetherwith their under :surfaees seated?" upon the top of the "rib 19.
